渗水地膜对土壤水分、温度及玉米产量的影响

The Effects of Water-permeability Plastic Film Mulching on Soil Water, Soil temperature and Maize Yield

田间试验表明 ,新型地膜—渗水地膜覆盖玉米可以提高土壤水分、调节地温、促进玉米发育进程 ,大幅度增加单位面积产量和提高水分利用率。渗水地膜覆盖技术是一项有前途的旱作农业技术。

A new kind of plastic film mulching, the water-permeability plastic film mulching, was proved effective in improving the status of soil water and soil temperature of maize fields by the conducting of the field experiment in dry land in Shanxi province.The yield of maize which was mulched with the water-permeability plastic film increased by 30% than that of the conventional plastic film mulching.
